. CORNET.

SPECIFICATION forming part of Letters Patent No. 426,398, dated April 22, 1890.

Application filed September 28, 1889 Eerial No. 325,375. (No model.)

To all whom it may concern.-

Be it known that I, JOHN F. STRATTON, of

- Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Cornet, of which the following is a full, clear, and exact description.

The invention relates to the French or Pyrenet piston-valve cornet; and its object is to provide a new and improved cornet, which when played upon produces a rich, full, and sweet tone.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a side elevation of the improve ment, and Fig. 2 is a sectional plan view of the same on the line 00 0c of Fig. l.

The improved corn et A is provided with the usual mouth-piece B, inserted in the pipe 0, leading into the first valve D, alongside of which are arranged the second and third valves E and F, respectively. The valves D and E are connected with each other by the short pipe G, and in a similar manner the valve E is connected with the valve F by a short pipe II. From the third valve F leads the end pipe I, which increases gradually in diameter until it finally terminates in the usual bell I. On pipe I may be arranged the valve J, for letting out the water.

On the valves D, E, and F operate the usual pistons,provided on their pistons stems with the usual finger-pieces K, L, and N, which the operator presses when it is desired to change the tone.

On the valve D is arranged the branch pipe 0, through which passes the wind when the finger-piece K is depressed. .A similar branch thin, cheap, and unmusical tone.

pipe P is arranged on the valve E, and a like one Q is held on the valve F. \Vhen the operator blows into the mouth-piece B and the pistons in the valves D, E, and F are in the normal position, the wind travels from the mouth-piece B into the pipe 0 to the valve D, and from the latterby the short branch pipe Gr into the valve E, and from the latter through the short branch pipe H into the valve F, and from the latter into the end pipe I. lVhen either of the pistons in the valves D, E, and F are pressed, the wind travels, in addition to the route above described, through the branch pipes O, I, and Q, respectively, according to the piston operated on.

In cornets as heretofore constructed the end pipe I commenced in the first valve D, and consequently was very short, so that the wind when traveling through the same produced a By the arrangement shown and described the end pipe I is increased in length considerably, so that the bell part of the end pipe is made considerablylarger withoutthrowing the instrument out of tune. It is understood that the grad ual increase of the end pipe I must be in harmon y with the length, otherwise no musical sound could be produced.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A Pyrenet pistonvalve cornet comprising the valves connected with each other, a mouthpiece pipe of uniform diameter and leading to the first one of the said valves, and an end pipe having a bell and leading from the third of the said valves and gradually in creasing in size from the said third valve, substantially as described.
